SPINNING AND T WISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 555,323, dated February 25, 1896.

Application filed July 21,1894. Serial No. 518,285. (No model.)

To all whom, it may concern:

Be it known that we, JOHN T. MEATS and ARTHUR MASON, of Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Spinning and Twisting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In spinning and twisting machines as now commonly made the crown gear carrying stand has been held concentric with the cylinder-shaft by means of a friction-clamp placed outside the cylinder-box, but such construc tion prevents any adjustment of the cylinderbox caps in case the bearing becomes heated. So also said stands, fitted loosely onto a turned part of the cylinder-boX, have been secured to the end casting or frame of the machine by a bolt inserted through a slot in the stand concentric with the cylinder-shaft, but much fitting is required to make the parts operative, because of the difficulty in getting the stands true or square with the cylinder-shaft. It has also been customary to bolt the crown-gear stand to the end casting of the machine on either side of the cylinder-box, in order that the fluted drawingrolls may be rotated in the proper direction, but with this latter construction in case of wear or when the crown or cylinder gears need to be changed, it becomes necessary to adjust the cylinder-gear with relation to the crown-gear, and also the usual change-gear, with relation to the intermediate gear, and in case the gears do not intermesh properly great wear results.

nary spinning or twisting frame with one of our improved crown-gear-carrying stands applied thereto, the usual drawing-rolls being omitted; Fig. 2, an end view of the crowngear stand with crown-gear, change-gear, and intermediate gear; Fig. 3, a sideview of the crown-gear-carrying stand. Fig. 4 represents the cylinder-shaft-box stand detached. Fig. 5 shows the cylindershaft box stand and crowngear-carryin g stand bolted together and also part of the cylinder and the cylinder and crown gears.

The end frame A, the cylinder B, its shaft cc, the cylinder'gear O, the crown-gear D, the change-gear E, the intermediate gears F, and the front-roll gears Gr driven by them, are all as commonly in use.

The lower part of the cylinder-shaft-box stand H (shown separately in Fig. 4) has an accurately-finished segmental surface or bed h h and a boss h, and the cap H of the box has a boss 72, corresponding with the boss h.

-The stand H is bolted to the end frame by suitable bolts 7L3, and has a hole 72, for a bolt 71 which is extended through a curved slot 2 in the crown-gear-carrying stand I), it having at its rear side, (see Fig. 3,) where the said stand is shown separately, an accuratelyfinished surface or foot I) to fit the bed h h, and accurately-fitted surfaces n n, surrounding holes 12.

The top of the stand 6 is shaped to leave a concave seat or bearing 27 to which is attached by bolts 5 a concave or segmental cap I), so as to leave between b and b a round hole to fit the bosses h kg of the cylinder-box and its cap, the stand being free to be turned about said bosses and the end of the shaft a in the box as a center when the bolt h is loosened sufficiently.

The cylinder-gear O is fast on the shaft a outside the stand 17 and engages and rotates the crown-gear D fast on a short shaft cl, revolving in bearing cl, said crown-gear having at one side the change-gear E, which is fixed to the crown-gear as pinions are commonly fixed to gears with which they work in train,

the change gear engaging the usual intermediate gear F, one intermediate driving the other, all as usual.

The shaft d carrying the crown and change gears is extended through a bearing (1, hav ing a portion of its end next the stand so reduced as to fit the hole n in stand I), said bearing being secured adj ustably to said stand by a bolt (Z extended through an ear of the stand and through an entering-slot 4 in the stand, the end of the bearing in contact with said stand being made to fit accurately the surface 01- of the stand.

The stand I) is, it will be seen, free to be moved about the shaft to as a center when the bolt 7L5 is loose, and said stand may be locked in place when the gears O and I) and E and F are in proper intermesh, and the strains may be kept direct, and wear may be compensated for, and yet if the cylinder-shaft becomes heated the screws 5 holding the cap H in place may be loosened and removed without taking off or disturbing the stand Z).

In operation it will be understood that the cylinderis rotated by a belt on suitable pulleys at its end opposite that shown in the drawings, and that the front rolls will be rotated through the gearing shown in Fig. 1, the gears O and D rotating very rapidly to effect the proper rotation of the train of gears driven by them, and it is because of this high speed and consequent wear that our invention becomes of importance in insuring proper intermeshin g of the gears and easy adj ustment, and when the stand I) carrying the shaft (l is adjusted the said shaft must move concentrically with relation to the shaft a, and by withdrawing the bolt (Z the bearing cl may be changed from one to the other end of the stand I), as may be required by the direction of the main driving-belt of the machine, the adjustment of the change-pinion E to engage one or the other intermediate gear insuring proper direction of rotation for the front draft-roller.

The bearings d may be cast solid on each side of the stand I), if it is desirable to cheapen the construction, by doing away with the planing of the surfaces 01-.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a spinning or twist-ing machine, the cylinder-shaft, its gear 0, a cylinder-shaft box stand provided with a bearing for said shaft, a laterally-extended boss h and a segmental cap having a boss 71 and a crown-gear-carrying stand having a bearing 19 and a segmental cap b to fit the bosses 71-, 77, and turn thereon about them and the cylinder-shaft as a center, combined with a crown and change gear supported by said crown-gear-carrying stand, and means to connect the said stands together and ,hold them in adjusted position, substantially as described.

2. In a spinning or twisting machine, a cylinder-shaft, its gear; a cylinder-shaft-box gear having a bearing provided with a laterally-extended boss 71 and having at one side an accurately-finished bed h, h, and a segmental cap H provided with a segmental boss 7L2, combined with a crown-gear-carryin g stand having at one side accurately-finished faces 5 to fit the finished bed It and having a curved bearing b and segmental cap to surround the bosses h, 7L2, combined with a crown and change gear supported by said crown-gearcarrying stand, and means to connect said stands together in adjusted position, substantially as described.

3. In a spinning or twisting machine, a crown-'gear-carryin g stand having a plurality of openings n, and a segmental bearing 1)", and cap 5*; and the cylinder-shaft-boX stand having an attached boss h, 7L2, to form a center of motion for said crown-gear-carrying stand; combined with a bearing d having a flange and a portion beyond to accurately fit either of said openings, and a shaft and a crown-gear and a change-gear fixed thereto, the said two openings serving to receive said bearing d according to the direction it is desired to turn the intermediate gears forming part of the roller-driving train, substantially as described.

4. In a spinning and twisting machine, the cylinder-shaft, its gear 0; and the cylindershaft-box stand having a shaft-bearing and a cap, each provided with a segmental boss, the stand having also a finished bed h; the shaft cl, its attached crown and change gears, and the flanged bearing d having a cylindrical end; the crown-gear-carrying stand having an opening n. surrounded by an accurately-finished face 71, into which opening the cylindrical end of the said bearing is fitted, and having a bearing b and a segmental cap Z) to fit the bosses h, h and an accuratelyfinished face I) to fit the bed It; combined with devices to hold the said bearing cl in said crown-gear-carrying stand, and to connect the latter stand when turned about the bosses h, 77/ to the cylinder-shaft-box stand, substantially as described. 7

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
